PORTABLE ELEVATOR.
SPECIFICATION forming part of Letters Patent N 0. 760,555, dated May 24, 1904.
Application filed July 25, 1898. Serial No. 686,798- (No model.)
To all whom it may concern.-
Be it known that I, CHARLES N. OwEN,a citizen of the United States, residing at Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Portable Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
Figure 1 is a side elevation of a portable crushing plant embodying my improvements and showing the same in working position. Fig. 2 is a similar view when the parts are in non-working position and ready for transportation. Fig. 3 isa plan view of the elevator in its non-working position. Fig. 4 is a sectional view. Fig. 5 is a rear View in elevation of the elevator and its truck or carriage.
My improvements relate particularly to a portable elevator especially designed and adapted for use in connection with rock-crushing machinery. As is well known, it is frequently desirable that a rock-crushing plant should be moved from place to place. In order to arrange the elevator by which the crushed material is removed from the crusher in proper relation to the other parts of the mechanism, it is necessary either to raise the crusher in some manner sufliciently far above the ground-level to allow the lower end of the elevator to extend below the chute ar ranged below the crushing-jaws or to make an excavation immediately below and in line with such chute on the crusher into which the lower end of the elevator may project. The first of these two methods is objectionable, because by raising the crusher it necessarily increases the distance or space through which the material must be raised vertically to be fed to the crushingjaws and also because such an arrangement necessarily increases the distance at which the upper end of the elevator must extend above the ground-line. It will be readily seen that such increased height under the vibrations caused by the 'tions.
crushing action will tend to dislodge the material deposited on the elevator and also require that the latter be made undesirably heavy in order to withstand the said vibra- Therefore I prefer to adopt the second of the two plans above referred to namely, to provide an excavation below the discharge-chute of the crusher, into which the lower end of the elevator will extend when in working position.
My present improvements relate particularly to a novel construction of elevator adapted to be easily and quickly adjusted into working position and held securely at any desired angle and which can also be quickly lowered to a horizontal position and connected with a stone-crusher when it is desired to move the latter.
Referring to the drawings, A designates a crusher, which may be of any desired or suitable type and which, as it does not form the principal part of my present invention, I have illustrated moreor less conventionally.
My improved portable elevator is supported and carried by a truck consisting of two ground-wheels B B, whichare connected by an axle C. To this axle is rigidly secured the main frame of the elevator, this being formed of two longitudinally-extending parallel side bars D, preferably formed of steel channel-beams. The longitudinal side bars D of the frame are connected and braced by crossbars E, and in suitable bearings near the ends of said bars D are mounted rollers F Gr.
H designates an endless conveyer, shown in the embodiment of my invention herein illustrated as being formed by a band or belt in of rubber or other suitable material and a series of buckets or receptacles it, secured by rivets to said belt. The elevator frame-bars D are rigidly secured to the axle C by inclined connecting-bars I, and it will be seen that the elevator is so positioned with relation to its supporting-truck that it is balanced thereon.
K K designate supplemental supportingbars, which are pivotally connected at their upper ends to the side bars D and are adapted to have their lower ends rest upon the ground when the apparatus is in use for the purpose of holding the upper end of the elevator at the desired height and angle. vator-is not in use, these bars K are supported in a position parallel to the side bars D by brackets D, as shown in Fig. 2. A chutescreen L is arranged to receive material from the outer or upper end of the elevator, and this chute is pivotally supported, so that the direction thereof with relation to the elevator may be varied as desired. As shown, it is pivotally connected near its upper end to links L, which are connected to the aforesaid bars K, and also provided with adjusting rods or bars M. In .each of the latter there is formed a series of perforations or apertures m, through which bolts or pins N can 'be inserted to secure said rods or bars to the supplemental elevator-supports K. As shown, the apertures m are arranged near the free ends of the bars or rods M, and a single aperture or passage m is formed in each of said supports in such position that when the pins N are engaged therewith and with the bars K the chute-screen L will be supported substantially parallel to and closely below the lower side of the belt it, as shown in Fig. 2.
To the lower or forward end of each channel-bar D is rigidly secured a guide-piece O, and in said guides are fitted the supports or bearings for the lower roller or drum G of the elevator. To these hearings are connected rods 1?, which extend rearwardly along the channel-bars D and through stationary brackets d secured thereto. The outer portions of these rods P are threaded, and with such threaded portions engage adjusting-nuts or small hand-wheels Q, Q, that at Q, being on one side of the bracket d and that at Q, on the opposite side. By means of these wheels the roller G can be bodily moved longitudinally of the frame-bars D to vary the tension of the conveyer-belt. The guides O are connected by orformed integral with a clevis or connecting-piece R, by means of which the elevator when not in use can be connected to the frame of the crusher A.
As shown, supplemental wheels or rollers S may be arranged upon the frame-bars D between the drums or rollers F G for assisting in supporting the loaded run of the conveyer-belt.
T designates a shaft which is mounted in suitable bearings t on the channel side bars D. This shaft T carries two band-Wheels T T, that at T being adapted to be connected with a suitable band-wheel A on the main drivingshaft of the crusher A. The band-wheel T is connected with a similar wheel U, mounted on the shaft of the drum F at the upper end of the elevator or upon another shaft extending parallel and geared to said drum-shaft.
While I have shown the conveyer or elevator proper as consisting of a belt or band It to which the buckets it are riveted, yet I do not wish to be understood as intending to When the ele- The manner of operating my improvements and the advantages thereof will be readily understood and appreciated. When the parts are in non-working position, as illustrated in Fig. 2, the elevator is balanced upon its supporting-truck and connected with the frame of the crusher A, which is shown as mounted upon suitable ground-wheels A so that as the crusher is moved the elevator will follow. When it is desired to place the parts in working position, it is merely necessary to disconnect the forward end of the elevator from the crusher-frame and depress such end. The truck-wheels B are then blocked, so as to be held from movement, and the auxiliary supports K arranged in position. The chute L is then adjusted at the desired angle to the elevator and the band-wheel T connected with the Wheel A on the crusher. When the crusher is set in operation, it will be seen that power will be transmitted to the elevator and crushed material delivered by the chute a of the crusher will be carried up and discharged over the chute-screen L.
To return the elevator to its non-Working position, the crusher A is moved forward slightly. The supplemental supporting-bars K are turned about their pivots and placed upon the brackets D. The lower forward end of the elevator is then easily raised and the frame D moved to a substantially horizontal position, when its clevis or connecting device R can be connected with a pin or hook secured site sides of the elevator and project beyond or across the excavation into which the lower end of the elevator extends.
I am aware that it has heretofore been proposed to mount a conveyer directly upon a crusher frame; but such constructions are very limited in their scope of receiving and delivering the material and are inoperative for taking the crushed material from the ground or other low point.
What I claim is 1. An elevator attachment for stone-crushers having in combination a truck-frame, an endless elevator, an elevator-frame mounted on the truck-frame and arranged substantially centrally over. the truck-axle, the elevatorframe being adapted to be tilted downward on the front side of the axle, and supplemental ground-supports for the elevator-frame in front of the truck-axle arranged substantially as set forth to support the elevator with its front end below the truck-wheels whereby it can be projected into a cavity in they ground below the crusher-chute, substantially as described.
2. An elevating attachment for a stonecrushing apparatus consisting of a twowheeled truck-frame, the endless conveyer, the conveyer-frame secured to the truck-frame and mounted substantially centrally across the axle thereof so that it may be approximately balanced thereon and adapted to turn on the truck-wheels either to bring the end of the conveyer at points below the crusher-chute or into an elevated position at the end of the crusher to be secured thereto, a ground-support for the elevator-frame at the inner end thereof, and adjustable ground supports or legs for the rear end of the elevator, substantially as set forth.
3. The combination of a pair of groundwheels, an axle connecting said wheels, an elevator having its frame rigidly connected to said axle, and adapted to be moved vertically about the axis thereof, supplemental supports, K, pivotally connected to said frame in rear of said axle, and means carried by the elevator-frame for holding said supplemental supports above the ground-line when the elevator is in a non-working position, substantially as set forth. I
4:. In a portable elevator, the combination of the supporting-truck, the elevator having its frame mounted on said truck, the auxiliary supports, K, connected with the elevatorframe at one side of the truck, and a screen connected to the elevator-frame'and to said auxiliary supports for receiving material discharged by said elevator, substantially as set forth.
5. The combination with a pivotally-supported elevator, of bars, K, connected to the elevator and adapted to support the upper end thereof when in working position, a pivotallymounted screen arranged to receive material discharged by the elevator, and adjustable connections between said screen and said bars, K, whereby the position of such screen with respect to the elevator can be varied, substantially as set forth.
In testimony whereof I afiix my signature in presence of two witnesses.
